Beit known that LWILLIAMF. KoEPPEN-,of

Marion, county of Grant, and State of Indiclear, and eXact descriptionthereof,reference being had to the accompanying drawings, in

which like numerals referto like parts.

This invention relates tofmeans for open; ing and closing 1nolds,and isespeciallyadapt-v ed for use with bottle or other kinds of' glass molds.

` The object ofthe invention is to provide means for so separating themold-sections in opening the mold as not to rinjure the glass articleblown or otherwise-formed therein.

It has been the common practice to hinge or pivot the two sections of aglass-mold toa common means and to open the mold or separate thesections thereof hy turning the moldsections back on their pivots. Suchmovement of the mold-sections causes them to move from the glass articlein a curve and often toinjure the portion of the glass bottle -or jartherein that-'may be in relief-as, for

example, the panels or the rectangular corners often seen in bottles.The means I have provided overcome this difficulty, as the moldsectionsare moved directly on a straightlateral line away from the thing moldedand away from each other. In order also to insure the opening ofthe'molds without in any v wise injuring the bottle or article therein,the

, and from the article therein.

means I have herein provided are such as to move one mold-section at atime. "First one section is removed while theV article is still held bythe other section, and then the seoond section is removed. This preventsin# jury to the glass article that so frequently ocV curs when the twosections of fthennold, are separated simultaneously from each other Thegeneral nature of theinvention willbe understood from the accompanyingdrawings and the following description and claims.

Figure 1 isa plan of' the device, one sec-'- tion of the mold beingopen.` Fig. 2 is a side elevation of the same. Fig. 3 is a cen-v tralvertical section of thesame. Fig. 4 is a bottom View when the'mold-.sections are closed. Fig. 5 is the same when one moldin Figsrl, 2,and 3.- -Fig. 6 is the sameshow# section has been opened tothepositionshown p 1'" f In thenaccompanyingdrawings. vthere kis shownatable or stand 10whose top isy cir- Y ,cularand which is supported bysegmental legs 11.-Y Upon said'stand or table a pair of parallelA-sh'ap'ed ribs 12 are Aprovided that extendY diametrically across theVtable'avnd equidistant from thecenter thereof. lAt the center of thetable or stand I secure a mold-f' i bottom' and centering-block 13,`heldin placefv by the screw 14, that extends through a` suit-V ablehole in the table or stand.10.v i l The mold is formed of thehalf-,sections l5.l and 16, secured, respectively, to the slidingv`plates 17 and AIS-by the screws 19,. On the under side Asaid slidingblocks areprovided with A-shaped grooves (not here shown) thatrcorrespond and fit over the ribs 12, and by this means the sections ofythe mold are guided in their movementtoward and awayV from` .y Theseslots are placed-0n opposite sides of the center of the disk 20, and theinner portion of slot 23 and outer portion of the slot j 22 areconcentric with said disk, and'one is near'said center and thev othervfar fromit.

The inner end of the slot 22 is curved slightlyA eecentricwith thelcenter of the ,disk and ap` preaches the said center as closely as thein- `i ner end of thefother slot; while the outer portionof the` otherslot 23 isv simil-arly curved and is `formed and far removed from thecen'- `9'@ ter of the disk so thatouter ends of the slots,

as shown, areequidistant fromthe center of i through the slots 22 and 23and have on the, llower ends headstoprevent their escape, as

The function of t appears in the drawings.

Pins 24, secured'in the sliding plate 20,' with the slots 22 and 23, isto move the sections of they molds away and toward each other bytheconnecting-pins 24".A Such movement and mode of movement willbeunderstood vfrom the following explanation: When the mold hasreceivedits charge of IOC glass and is closed, the sections beingagainst each other on the under side of the disk 20, the bolts 2i are attheir inner limit of movement in the slots 22 and 23.' The pins are thenequidistant from the center, andthe parts are in the position shown inFig. 4. After the article has been blown and it is desired/lo open themold the handle 2l and disk 2O are moved from the position shown in Fig.l to that shown in Fig. 5. During such movementofthe disk the bolt 24 ismoved only through the portion of the slot 23 Which is concentric withthe disk 20, and since said bolt has not been moved farther away fromsaid center the moldl5,`to which said pin is secured, has remainedstationary, as shown in Figs. 1 and 2; but such oscillation oi' the disk20 has caused the other bolt 24, extending down from the mold-section1G, to be moved from the position shown in Fig. et to that shown in Fig.5, and such movement has withdrawn said mold-section 16 on a direct linelaterally from the other moldsection and The article molded to outerlimit of movement. Then the disk 2O `is further oscillated from theposition shown in Fig. 5 to that shown in Fig. 6, during which the bolt24; from the mold section 15 travels through the slot 23 to its outerend, and consequently moves the mold-section 15 away from the moldedarticle to its outer limit of movement. During such movement of themold-section 15 the other mold-section has not moved, as its bolt 24:has merely passed through the concentric portion of the slot 22. Thearticle molded may then be removed and the mold-sections brought intoposition for another charge by reversing the movement ot the lever 2lfrom the position shown in Fig. G to that shown in Fig. l, and duringsuch reversal the mold-section 15 will first be brought to the closedposition, ready for a charge of glass, and then the mold-seclion 16 bemoved to the closed position.

IVhat I claim as my invention, and desire to secure by Letters Patent,is

l. In a mold opening and closing device a pair of mold-sections, a guidefor the lateral movement thereof in opposite directions, pins extendingfrom said molds, and an oscillatory plate with slots therein into whichsaid pins loosely extend, said slots being so arranged that when theplate is oscillated it will cause one of said mold-sections to be movedin advance of the other.

2. In a mold opening and closing device, a pair of mold-sections, astationary plate beneath the moldsections with slots therein in linewith each other and with the center of the mold, pins connected with themold-sec tions and extending down through the slots in the stationaryplate, and an oscillatory plate below the stationary plate with slotstherein for receivingthe lower ends of said pins, said slots being soarranged that when the plate is oscillated itwill cause one of saidmold-sections to be moved from the center in advance of the other.

3. In a mold opening and closing device, a pair of mold-sections, aguide for the 'movement` thereof, a plate mounted concentric with themold-sections when closed having a concentric slot on one side of itscenter and an eccentric slot opposite thereto, the inner end of theeccentric slot being diametrically opposite the inner end of theconcentric slot and equidistant from the centerof said plate, and meansextending loosely through said slots and rigidly connected with saidmoldsection for moving the latter when said plate` is moved.

4. In a mold opening and closing device, a

pair of mold-sections, a guide for the moldseetions, a plate mountedconcentric With the mold when closed having on one side ot the center aslot that is concentric at its `inner end and eccentric at its outerend, and an eccentric slot on the other side of the center of said platewith its inner end diam etrically opposite the inner end and at the samedistance from the center ot the plate as the concentric portion of thefirst-mentioned slot, means for giving said plate rotary movement, andmeans extending loosely through said slots and rigidly connected withsaid mold-sections.

5. In a mold opening and closing device, a stand having openings in it,a straight guideway, plates slidable on the stand and controlled by saidguidevvay, mold-sections secured to said sliding plates, a platerotatably mounted under the stand and concentric with the mold whenclosed, means for oscillating said plate, a pair of slots in said plateon opposite sides of the center, one slot having its inner portionconcentric and its outer portion eccentric with the center of the disk,and the other slot having its inner portion correspondingly eccentricand at its outer portion concentric with the center of said disk, andbolts extending down from .the sliding plate through the openings in thestand and through said slots.

In Witness whereof I have hereunto aixed my signature in the presence ofthe witnesses herein named.
